摘　　要：GIS变电站复杂的空间电磁骚扰会耦合侵入智慧型变电站无线传感网络的汇聚节点设备,导致其丢包、误码、工作异常。本文分析了变电站电气结构与电磁环境,给出了某实际变电站的电磁实测值,建立了GIS隔离开关对二次设备及线缆的电磁干扰路径,并推导了耦合原理,基于某实际变电站的调研,建立了汇聚节点线缆稳态情况下的耦合仿真模型,并仿真和计算了进出线套感应电压,为推进电力物联网的大面积建设提供了技术保障。Complex spatial electromagnetic disturbance in GIS substation can couple the convergent node devices which invade the wireless sensor network of smart substation,resulting in packet loss,error code and abnormal operation.This paper analyses the substation electrical structure and electromagnetic environment,gives the measured electromagnetic values of a real substation,establishes the electromagnetic interference path of the GIS isolation switch to the secondary equipment and cables,and deduces the coupling principle.Based on the investigation of a real substation,the paper analyses the electrical structure and electromagnetic environment of the substation.A coupled simulation model is established for the steady state of convergent node cables,and the induction voltage of in and out sleeves is simulated and calculated,which provides technical support for promoting the large-scale construction of the power internet of things.
